A group of friends, including Fischer's Silk, Motoki, Zakao, and Ndaho, visit Amuse Park Adachi to participate in a treasure hunt. They are tasked with finding a rare "phantom key" by digging in a gravel pit and sifting through the dirt. Along the way, they find various jewels and birthstones, which they excitedly discover and explain the meanings behind each one. Eventually, Motoki finds the phantom key, and the group decides to fast-forward the rest of their digging to show the results.
